I haven't ever been able to tell a difference with cable either. I have only used entry level MIT($50 IC)and upgraded to Audioquest($200-300 IC). I admit this was purely aesthetic and just because I enjoy buying stuff for my stereo. My local dealer offered to teach me how to discern between cables years ago and I declined. I tried the Blue SR fuses a couple years ago and couldn't hear any difference. Maybe some of us simply aren't trained enough to hear the subtle changes? I have different electronics now compared to when I tried the Blue. I also only have one fuse so am thinking about trying the Orange just for fun due to the return policy.
